BRUSH-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 317,570, dated May 12,1885.

Application filed October 13, 1883.

To @ZZ whom, it may concern:

Be it known that I, JOSEPH M. PrcKEEiNer,y

a citizen of the United States,residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented a new anduseful Improvement in Needles for Use in Brush-Making, of which thefollowing is a specification.

One feature of my invention relates to novel means whereby the wire isclamped to the needle handle for enabling proper tensile strain to beapplied to the wirejwhich is used for confining the tufts of bristles ina brush block or stock; and said means consist of a two part handleprovided with clampingplates, which afford a reliable grip upon the wirewhen closed thereon under pressure by the hand of the operator.

Another feature of my invention has for its object an always accessiblespace for the reception of a tuft of bristles near the outer end of theneedle after it has been passed through a tuft-hole in a brush-block.Heretofore such needles have been practically straight, and thereforemore or less manipulation was requisite for placing the tufts ofbristles in such position between the needle and the wire as wouldafford the loop needed to enable the tuft to be thereafter drawn intoits seat in the brush-block; but my improved needle is bent at its outerend at an angle or curve from its straight shank and in the planeoccupied by the eye, so that a wire passing rearwardly from the eye in astraight line is so far removed from the adjacent side of the needle asto always afford a tuft-receiving space. As essential features inconstruction my bent needle is channeled or longitudinally grooved fromthe eye rearwardly at the back of the bent end for partially housing thewire, and the needle-eye is rounded at its, rear end and inclined at itsouter end, and a brush-makers needle with such an eye is novel,whetherwith or without the bent feature.

I am aware that sewing-machine needles have been bent so as to beoperated in the are of a circle, and also that all needles have eyes sorounded and finished as to avoid cutting thread; but I know of no priorneedle having the inclined outer end at its eye and otherwise soconstructed as to be of practical service as a brush-makers needle,which, being (No model.)

used with wire, must enable considerable tensile strain to be appliedthereto without malcing a bend or bight in the wire, and this isobviated by providing the eye with an inclined outer end.

In the accompanying drawings, which make a part of this specification,Figure l is a side View of the needle A and handle B. Fig. 2 is atopview of the needle and handle, the jaw 2 being thrown upward andbackward. Fig. 3 is a vertical section at the broken line w x of Fig. 1.Fig. 4 is a longitudinal section of the needle A. l

Like letters of reference in all the figures indicate the same parts.

A represents a needle for wiring the tufts of bristles into the stock,the wire beinglooped over the tufts in the usual manner, grasping them,respectively, as the needle is drawn through the holes of the stock. Itis provided with a handle, B, composed of two parts, 1 and 2,hingedtogether by means of the jointpin a. The outer end of the needle isinserted in the hole b of the part 1 of the handle, and confined bymeans of the set-screw c.

G O are steel plates the faces of which are arranged to form teeth inthe manner of files, whereby to hold securely the drawing-wire D, whichis passed through-.holes in the part 1 of the handle. They aredovetailed into the inner faces of the handle, as shown in Figs. 1 and2, to hold them securely in place, and they grasp the wire tightlyduring the drawing in of the tufts.

The eye end of the needle is bent in the manner shown in the drawings.

As hereinbefore stated, brush-makers needles have heretofore beenstraight, as shown," for instance, in the United States Letters Patentof Joseph Pickering, October 24, 1871, No. 120,164., and therefore withsuch needles the wire must be manipulated for properly looping a tuft ofbristles, while, as seen in Fig. 4, the bent needle affords areadily-accessible space between the wire D and the bent portion of theneedle for the ready reception of a tuft of bristles. It will also beseen that the bend or curve of the needle is in the vertical planeoccupied by the eye, so that the wire can pass directly downward throughthe eye, and thence rearwardly beneath the bent or curved portion of theneedle.

Said needle has a longitudinal groove, e, cut in its upper side toreceive the wire D, the eye j' being carried forward from the groove onan angle, as shown in Figs. 1 and 4, terminating near the end of theneedle at the opposite side from the groove. If the inner end of the eyehad a sharp corner or corners, as the needle is pushed iorward the wirein pressing thereon would be weakened, and to prevent this I round theend of the eye completely from side to side of the needle, as shown inFigs. l and 4L, and. thusl prevent any injury to the wire. The outer endof the eye being inclined, as clearly shown in Fig. 4, enables a strongpull to be given to the wire without causing a bend therein, it beingobvious that the wire Will occupy a practically straight line in passingoutwardly and forwardly from the groove or channel e through the eye.

I claim as my inventionl. The brush-makers needle having a handle in twoparts hinged together,and provided with grasping or clamping plates,substantially as described, whereby wire isv securely held during theoperation of wiring tufts of 25 tends rearwardly from the eye, as setforth.

3. In a brush-maker'sV needle, an eye near the point thereof, having arounded inner end` and an inclined outer end, substantially asdescribed, whereby tensile strain can be applied to Va wire passingalong said needle and forwardly through said eye without materiallybending said wire, as set forth.
